Those borrowing over 90 per cent loan-to-value (LTV) will find that many lenders will hit them with yet another fee a higher lending charge (HLC).
find out how much you can borrow
Research by moneyfacts.co.uk has found 66 per cent of all prime lenders will charge an additional fee for high LTV mortgages, typically ranging between 7 per cent and 8 per cent, but it can reach as high as 12 per cent in several cases.
While a fee may only apply to LTVs in excess of, say 90 per cent, most lenders will back charge this to a lower LTV of 75 per cent to 80 per cent.
Julia Harris, mortgage analyst at Moneyfacts.co.uk the money search engine, said: Being subjected to a HLC can prove a very costly addition to the fees already associated with house buying, and can more than wipe out the initial savings made on what was a competitive rate.

But dont be lulled into thinking that, by choosing a lender which does not charge a HLC you will not be faced with higher charges, as it may mean you pay a higher interest rate instead.
While the headline rates and the lack of a higher lending charge may attract borrowers through the doors, the amount which they will actually repay could be very different.
Harris said: While lenders can argue that HLCs and higher rates are paid for slightly different reasons, it makes no difference to the borrower where the extra costs ends up, either as an insurance or simply to reflect the higher risk. Its still an additional cost to the borrower.

So before jumping into a deal just because you wont pay a HLC, its best to check out the full details of the deal. Ensure you know the total cost of your mortgage deal and take account of any fees which may be added to the loan or the term over which you may have to pay the inflated rate.
Harris explained: Borrowing to high LTVs obviously presents a higher risk to the lender should house prices fall and the borrower finds themselves in financial difficulty. But with a rising housing market the risk must be fairly small, especially as this is backed up by the fact that more lenders prepared to lend 100 per cent of the property price or more.
